Yes! Here you go. Just don't delete Collections Manager, place it in a collection then hide it with collection manager. It won't hide without being in a collection.

Thanks too, Titano. Although I did not hide the CM, but rather put it in a Kindle Tools collection along with JBPatch. Still it is useful for me to access it via Launcher rather than scrolling to it in the main menu. Im no coder but I will look at how you made that extension and try to create one for adding JBPatch to Launcher as well. Hopefully wont break something
